What you wrote is probably the main problem when watching streams and that the attitude of streamers to subscribers can in no way be called sincere and truly humane. For almost all streamers, a subscriber is just a handy tool for making money and if a subscriber has somehow worked off the streamer's recommendation, for example, used a referral link, then this person is basically no longer needed by the streamer.
You got me confused here, did you mean that so long as the subscriber of the streamer clicked on the referral link actually "embedded by the streamer," the streamer doesn't have anything to do with the subscriber again? If yes, how? Sincerely, I don't see how this correlates.
Bookies are partnering with streamers and naturally, if the streamer embeds the bookie's link, it shows that there is more monetary interest. Besides, if the subscribers signed up to the bookie through the link, that still doesn't mean such a subscriber will not be a returning viewer of the streamer.
Well, of course, such a subscriber will probably continue to watch these streams.
I will clarify my statement more correctly. Since any serious streamer has many subscribers, thousands of people or an order of magnitude more, then the streamer's attitude to the sum of these people becomes purely formal, excluding any individual manifestations of human sympathy or real friendship. As a result, these subscribers cease to be perceived by the streamer as autonomous individuals, as personalities, and turn into a formal tool for earning money.
And in principle, it does not matter how the streamer earns money - referral links or simply by paying for advertising from a casino or bookmaker or other payments. This is my vision of this process.
